18 Of The Largest Sea Creatures Prowling The Ocean While You Swim

Anyone who has ever seen the film jaws will have experienced that sense of dread while treading water in the sea. There’s something very terrifying about not being able to know precisely what’s under there and our imagination is terrifyingly good at filling in the blanks.

But sharks are the least of your worries. Check out these absolutely massive creatures…

Hover over them to learn who and what they are

This is NOT a jellyfish, that it is often mistaken for. Its actually a full colony of organisms all working together to live to feed, and sting if necessary.While the body is only about 12 inches, its freakishly long tentacles can reach lengths of up to 165 ft below. Thats over 17 stories, higher than most skyscrapers in NYC.

This is JAWS. While they don’t kill as many people as our fears let us believe they do, This little guy can reach lengths of 21 ft. and over 7,328 lb. Think you can outswim it? Think again. He coasts at a moderate 35 mph

Ewww. Worms. 7 ft 10 in worms. Dont worry, they usually live miles deep down near black smokers (no puns please) which are like mini volcanos pouring smoke into the ocean.

This monster is the largest mollusks in the world and has been measured at 4 feet across and weigh over 500 pounds! Thats enough to swallow a small child.

At up to 20 feet long and weighing up to 8,800 pounds, they got their name from their elephant like face.Where can one these guys sit? Anywhere he wants to. Just don’t be underneath him.

While most start off really small and never get too big, these bony fish grow up to 36 feet. The one these guys in the picture are holding is only 23ft. Thats a lotta sushi.

These are the largest invertebrates on Earth and the largest ever found was 18 meters in length and weighed almost a ton! I think this one is related to squidworth.

This is a prehistoric distant relative of the shrimp/crab that grows up to 30 inches and 1.7 kilograms. It also looks absurdly like something from Men In Black.

Don’t be too frightened of this shark if you happen to come across it. Its a filter feeding shark. So it just swims around letting stuff float into its mouth while it feeds. Its been known to grow as big as 41.50 ft. weigh more than 47,000 lb. Thats a lot of sushi.

Not had your fill of humongous octopi? Then how about this one that grows up to 30 feet and weighs 272Kg. It can eat sharks you know!

If you were to stand next to a Fin Whale you’d be all like… ‘say what??’. That’s because it measures up to 27.3 meters and weighs 74 tons!

Also known as ‘hair jelly,’This is the largest known species of jellyfish with a bell (body) with a diameter of 7 ft 6 in and tentacles 120 ft . Take a ride to the smithsonian if you want to see one in person without getting wet.

The blue whale measures up to 30 meters and weighs 200 tons! If hes hungry, be careful because he can eat 40 million krill a day.

At 42 pounds, this is one big crab. One leg can probably feed 3 dinner services at red lobster. Just one leg can reach a massive 12 feet The body may grow to a 16 inches.

Its a sponge. Nothing too scary, unless you accidently fall into its 6 foot x 6 foot hole of a mouth that will probably devour you faster than you can say Spongebob Squarepants.

No, this is not Parick Star, but he is a big boy. Reaching at sizes up to 2 feet, they hang around eastern coast of North America from Southern California to British Columbia.

heheheh – you said Sperm…..Growing at up to 57 feet, and diving up to 7,380 ft to eat, this is the largest living creature on the planet.

Like a mini underwater airplane of the sea, these got wingspans of 30 feet.
